I am calling ajax function which return some data in JSON format from wcf rest service. I am getting data when I user IE browser but it's failed to get data when I use Mozilla and Chrome browser.

Following is the code I am using.

    <script src="js/JSon.js" type="text/javascript"></script>
    <script src="js/jquery-1.6.2.min.js" type="text/javascript"></script>
    <script src="js/jquery.js" type="text/javascript"></script>

 function fillcategory() {
                var GetCategoryURl = "http://localhost:4444/Service1.svc/GetCategory"
                var drp = "";
                   $.ajax({
                        cache: false,
                        type: "GET",
                        async: false,  
                        url: GetCategoryURl,
                        dataType: "json",   
                        success: function (objCategory) {
                            Category = objCategory;                               
                        }
                    ,
                        error: function (xhr) {

                        }
                    });

                 fillSubcategory();
            }

Rquest Header is:

只需将它添加到您的服务器端代码（服务）的 global.asax 文件中，它就可以肯定地工作，

 protected void Application_BeginRequest(object sender, EventArgs e)
    {
        HttpContext.Current.Response.Cache.SetCacheability(HttpCacheability.NoCache);
        HttpContext.Current.Response.Cache.SetNoStore();
        EnableCrossDmainAjaxCall();

    }

    private void EnableCrossDmainAjaxCall()
    {
        HttpContext.Current.Response.AddHeader("Access-Control-Allow-Origin", "*");
        if (HttpContext.Current.Request.HttpMethod == "OPTIONS")
        {
            HttpContext.Current.Response.AddHeader("Access-Control-Allow-Methods", "GET, POST");
            HttpContext.Current.Response.AddHeader("Access-Control-Allow-Headers", "Content-Type, Accept");
            HttpContext.Current.Response.AddHeader("Access-Control-Max-Age", "1728000");
            HttpContext.Current.Response.End();
        }
    }
